2005 Cummins won't start

[glennk]

My 2005 Monaco Knight won't start. The engine is the 330 hp Cummins ISC. It turns over but will not start. I noticed the wait to start light does not come on when I turn the key on. The coach ran just fine 4 months ago but had to park it due to illness. The start batteries are 2 years old and fully charged. Please help and thanks.

Two possibilities.
1. Lost fuel prime while sitting. Try cycling the key to on for about 20 seconds then off. Do not turn to start. Do this about 6-8 times. Should run the pump.

2. Fuel filters could have some build up of algae and be blocking flow. Change fi
Tears & pre fill new filters with fresh fuel. Be sure to fill through the outside holes.

Let us know how you do.

Not sure about yours, but the loss of the wait to start light means the ECM is failing on a Dodge/Ram truck. Check the plugs on your ECM for any corrosion or loose wires.
